First, THANKS! I posted a note here a few days ago seeking
input on the pros and cons of getting my daughter and her
next-door-neighbor friend either cb or 49 mhz two-way radios.

I've had nearly two dozen replies, all very thoughtful. I
had many who expressed reservations about children having CB
radios from the perspective of others they would hear. I suspect
that is unfortunate but true. CB language is sometimes pretty bad.

On a purely scientific note (and also because it was clearly the
cheapest option!) we tried a set of those "Space Patrol" quality
walkie-talkies. These had morse code and a beep button on the
front. They were WOEFULLY inadequate. They did work, but they
were only good for about the distance two people could easily
talk *without* radios! Too bad. Nice try.

I did stop at a radio shack and tested their 49mhz radios, and I
suspect something of that quality would be far better for them.
(These were the entry-level one channel "***" models.)
I may just opt for buying the radios new, as they are not
terribly expensive, but I thought I'd post here first just to
see if anybody has anything they think might do the trick.
I've also told the girls they should put up some money of their
own if they want walkie-talkies...and maybe they'll take better
care of them. (But their budgets are limited!  ;-)  )

Again, thanks to all who replied to my earlier post. Your comments
were much appreciated!

- Dave

Quick follow-up in case anyone was interested in the outcome of
my search...and a couple of people were curious...

We reached a rather unorthodox and unexpected solution. The girls
got a wireless intercom system, the type that plugs into the wall
and transmits through the wiring. It is not mobile, but the
quality is excellent, it has the call function, etc.

We picked these up as a test, actually. They were less expensive
than the RS 49 mhz radios, too. I expected they would work in my
house, and they did, that was the first test. Then wer tried from
the house to the garage...still good. I was really surprised when
they worked just as well from house-to-house.

Perhaps it is obvious that I know nothing about electrical wiring.
Maybe both houses run off the same transformer or something. I
haven't a clue why they work, but they do. Very nicely, actually.
No background noise, can leave them on all the time, no batteries
to go dead, etc. They seem quite pleased.

Thanks again to all who offered comments and suggestions.  - Dave

It's because they are on the same side of the transformer.
I use them in my house, to talk between floors, and they work fairly well.
Ofcourse, there is a risk. With one of these, you could potentally listen
into other neighbors...

    What a unique idea!  

   From what i understand, the intercoms use a low power RF in the
Longwave band for transmissions.  The electrical wiring in the house is
used for an antenna.  Communications can be conducted between units as
long as they share the same transformer.  It appears you and the neighbor
share the same transformer.

Super!  You have satisfied their needs for a very low cost... PLUS you
eliminated risks of exposure to unwanted interference/language.  Also...
_technically_ they are communicating via radio, so all the requirements
were met.... Plus the kids like the arrangement.

I'd have never thought of that idea.  So much a very obvious solution though.

One more benefit.... They won't be tying up your phone lines! :)

Cheers!

Not only will the kids not be using the phone lines (so I can use
my computer on-line like I am now!) but also I won't have to be
investing in Energizers all the time!  - Dave
